J. A. Moffett Jr. was an oil tanker built in 1920–1921 by the Federal Shipbuilding Company of Kearney for the Standard Oil Company of New Jersey with the purpose of carrying oil and petroleum products. Originally built as a steamship, the vessel had her engines changed in 1927 converting her into a motor vessel. She was torpedoed in 1942, killing the captain, before being abandoned, towed and sold for scrap.
